Tournaments (Duck Life 4 Remastered)
Win three-round team tournaments to unlock the next world.
Entering
Beat the world’s ticket opponent, then visit its tournament. Assign a duck to each of the three rounds. You may use ducks from your 
Ducks.
Winning
The tournament unlocks the next world when the three stored ranks produce a first-place result. Train the relevant skills and feed your team before entering.
World tournaments
The Volcano uses key races and the Fire Duck challenge instead of another ordinary tournament.
